To answer the question of why we need to visualize the trained decision tree, I am going to show you the visual representation of the above fruit classifier.īefore I show you the visual representation of the trained decision tree classifier, have a look at the 3 test observations we considered for predicting the target fruit type from the fruit classifier. The syntax of the if-statement is given below.The below image is the visual representation of the trained fruit classifier. The condition of if statement can be any valid logical expression which can be either evaluated to true or false. The if statement is used to test a particular condition and if the condition is true, it executes a block of code known as if-block. We will see how the actual indentation takes place in decision making and other stuff in python. All the statements of one block are intended at the same level indentation. Indentation is the most used part of the python language since it declares the block of code. Generally, four spaces are given to indent the statements which are a typical amount of indentation in python. If two statements are at the same indentation level, then they are the part of the same block. In Python, indentation is used to declare a block. Nested if statements enable us to use if ? else statement inside an outer if statement.įor the ease of programming and to achieve simplicity, python doesn't allow the use of parentheses for the block level code. If the condition provided in the if statement is false, then the else statement will be executed. The if-else statement is similar to if statement except the fact that, it also provides the block of the code for the false case of the condition to be checked. If the condition is true, a block of code (if-block) will be executed. The if statement is used to test a specific condition. In python, decision making is performed by the following statements. Condition checking is the backbone of decision making. Here, the decisions are made on the validity of the particular conditions. As the name implies, decision making allows us to run a particular block of code for a particular decision.
